For TV/video
xawtv of course, it is still the main application. A nice X11 application for watching TV.
motva new, IMHO better, motif-based GUI for xawtv.
fbtv is a TV application for the linux console, it uses the new 2.2.x framebuffer devices.
v4lctl, a command line tool to set video4linux parameters (tune in some channel, set TV norm, ...).
streamer, a command line tool for capturing still images and avi-videos (with sound).
radio, a simple, curses-based radio app.
webcam, captures images and uploads them with FTP to a Web-Server in a endless loop.
alevtd, a http server for videotext pages. VBI decoder taken from Edgar Toernig' alevt application.
xawtv, fbtv and v4lctl share the same config file.
